Qwen-Image 3.0 (Text-to-Image)
Qwen-Image 3.0 is a high-fidelity text-to-image model that generates images from detailed text prompts. Built-in prompt expansion (DPE/APE) enriches short prompts, while flexible resolution and reproducible seeds make it suitable for both rapid exploration and controlled iteration.
Invite-beta model for interface testing. Output does not represent final quality.
🌟 Key Features
✏️ Text-to-Image
Generate high-fidelity images from text prompts alone, with strong semantic understanding and photorealistic quality.
🧠 Prompt Expansion (DPE / APE)
prompt_extend intelligently rewrites short prompts. Choose direct (DPE, single-pass) or agent (APE, agentic pipeline).
📐 Flexible Resolution
Specify size as width*height (up to 2048×2048), or omit it to let the model pick automatically from the prompt.
🔁 Reproducible Results
Pin a seed value to reproduce or iterate on a specific generation, enabling systematic prompt refinement.
🖼 Batch Generation
Request multiple images per call with n to explore variations at once.
⚙️ Parameters
| Parameter | Required | Description |
|---|---|---|
prompt | ✅ | Text description of the image to generate. |

n | ❌ | Number of images to generate (default: 1). |
negative_prompt | ❌ | Content that should NOT appear in the image. |
seed | ❌ | Seed for reproducible output, range [0, 2147483647]. Omit for random. |
prompt_extend | ❌ | Enable intelligent prompt rewriting (default: true). |
prompt_extend_mode | ❌ | direct (DPE, default) or agent (APE). |
💡 Prompt Tips
A vertical outdoor portrait in warm afternoon light: a young woman turns to the camera with a bright smile, holding a large bouquet of orange and peach roses, backlit hair rimmed with gold, a blurred sunlit city street behind her, warm film grain.
- Be specific about subject, environment, lighting, and camera angle for best results.
- Fix
